I think SE will call them something completely different. I wish we would get more info on what they will be called and maybe some explanation as to how it will be setup. Oh well, waiting for more info as usual.
If FFXI is any indication, hang on to that feeling of "waiting for more info" and learn to love it :)
Seriously, I really do wish SE was more forward about releasing information. They really seem to hang on to the idea that "not knowing" makes the game "more fun", and under normal circumstances I would be inclined to agree, but they stretch that logic to EVERYTHING from accuracy to elemental resistances to what days/times actually mean to how to beat AV.
There's still so much **** in XI that, to this day, people STILL don't know what the **** it's for (See: Doll Gizmo, Ebon Panels, etc).
Again, I'm not saying they need to tell us EVERYTHING and completely ruin the game, but a little more disclosure a little more frequently would not be an unwelcome thing.
